Circulating fluidized-bed reactors (CFB) are typically operated at high temperature and often at high pressure, and the only measurements are gas and solid inflow rates, differential pressure and temperature. Kalman filtering is used first to infer solids circulation rate, standpipe bed height, and standpipe gas flow from the given measurements, and second to control the operation of a CFB optimally. The development and implementation of a Kalman filter for an atmospheric, ambient temperature CFB is reported.
